Alternative approach is the PC-CGTM1 process, as shown in Fig. 2, whose major components are the AGRU, ASU, MPOU, MSU, and a new pulverized coke gasification unit (PCGU). In the PC-CGTM1, the new PCGU generates CO-dominant syngas, which is mixed with the syngas from the MPOU to adjust the R value to be 2, which is ideal for methanol synthesis.
4. Manufacturing Process. 1.Pulverizing Raw materials such as coke are pulverized. 2.
